+# Ribica Back Office
+
 Rails interface for administration
+
+## Configuration
+
+Configure config/database.yml to point to same database as config.rb in front office 
+
+## Active scaffold
+
+Customization documentation is here: http://activescaffold.com/
+
+Example of generating scaffold for category model 
+
+`rails g active_scaffold Category name:string`
+
+## Handling shared models
+
+Some of models will necesarrily be shared between front and back office. 
+Migrations for those models *must be in front office* and 
+back office will just have a model file with custom code if needed.
+The reason is that we want front office to be standalone with a different
+backoffice (for sellingtechnology to other businesses and stuff).
+
+When generating active scaffold - migration is generated by default so it 
+needs to be removed before using it.
